Zinc concentration in serum and hair was measured in a cross-sectional study of 437 Chinese women of whom 310 were normal controls studied at various stages of pregnancy and up to 12 months after delivery. The rest had spontaneous abortions, fetuses with a birthweight below the 10th centile for gestation or congenital abnormalities. Zinc concentration fell throughout normal pregnancy, the fall being greater in serum than in hair. There was no correlation between serum and hair levels. The infant birthweight had a positive correlation with serum level but a negative correlation with hair level. Abortion, low birthweight and congenital abnormality were not associated with low concentrations of zinc in plasma or hair.
在一项横断面研究中，对437名中国女性的血清和头发中的锌浓度进行了测量。其中310名是正常对照组，在怀孕的各个阶段以及产后长达12个月进行研究。其余的女性有自然流产、出生体重低于妊娠第10百分位数的胎儿或先天性异常。在正常怀孕期间，锌浓度会下降，血清中的下降幅度大于头发中的。血清和头发中的锌水平之间没有相关性。婴儿出生体重与血清水平呈正相关，但与头发水平呈负相关。流产、低出生体重和先天性异常与血浆或头发中锌浓度低无关。
